UNITED STATES PATENT OFFIC FRANCIS H. RICHARDS, OF HARTFORD,CONNECTICUT, ASSIGNOR TO THE PRATT & WHITNEY COMPANY, OF SAME PLACE.

REGULATOR FOR GRAIN-WEIGHERS.

SPECIFICATION forming part of Letters Patent No. 434,723, dated August19, 1890.

Application filed March 21, 1890. Serial No. 344,7] 7. (No model.)

T0 at whom it may concern:

Be it known that I, FRANCIS H. RICHARDS, a citizen of the UnitedStates,:- residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inRegulators for Grain-Weighers, of which the following is aspecification.

This invention relates to regulators for automatic grain-weighers, theobject being to control or regulate the operation of the grain-weigherby means of the accumulation of the discharged grain.

In the drawings accompanying and forming a part of this'specification,Figure 1 is a plan view of the frame-work of a grain-Weigher havingthereon my improved regulator apparatus. Fig. 2 is a front elevation ofthe machine. Fig. 3 is a left-hand side elevation of the same. Figs. 1and 5 are sectional side views illustrative of the operation of myimproved regulator.

Similar characters designate like parts in all the figures.

The regulator apparatus herein shown and described is also shown in myapplication, Serial No. 342,657, filed March 1, 1890, where it is usedin connection with a complete automatic grain=weigher, and such parts ofthe said machine as are shown herein are designated by the samereference characters.

The regulator-hopper P is pivoted at 98 and 99 to the framework, and isfurnished with one or more weighted arms, as 10 10, having thereonsuitable counter-weights, as 11 11. Said regulator P, acting through therods 13 and 14, pivoted thereto at 52 and 53, operates the regulatorvalve or gate 200. The lower ends on the rods 13 and 14 are pivotallyattached to the hopper, and at their upper ends they are secured to thevalve-bar 197. As a means for guiding the regulator-gate, the said rodspass through mortises in the projecting arms 198 and 199 of the topplate 5, said arms acting as guides for the said rods. The supply-chuteH is shown of a form and construction suitable for using the regulatorherein described and claimed. The upper portion of the said chute hasthe openings 191 formed in the end walls 192 thereof, said openingsbeing surrounded at top and at the two sides thereof by the walls 193.The said walls 193 extend from side to side longitudinally of the chute,connecting the said end walls 192 and dividing the said chute centrallyand forming the side passages 194 and 196. A rim or flange 195 is formedaround the top of the outlet of the chute, the groove or depression 201being thus formed in the chute around said flange. The lower portion ofthe outlet of the chute is shown divided into two parts, forming theseparate outlets and 65', as and for the purposes described in my saidapplication; but that feature is not material to my present invention.The bar 197 extends from side to side through the opening 191 in thesupply-chute H and carries thereon the boxshaped valve or gate 200,which gate is open at the bottom and, preferably, also at the top, asshown. On the lowering of the hopper the rods 13 and 14 draw down thesaid regulatorvalve 200 from its position in Fig. 4 to its position inFig. 5, thereby bringing the valve edges close down around the rim orflange 195, so that the lower edges thereof sink to the groove 201, thuscutting 0d the flow of grain from said chute into thedischarge-spout 65thereof. The grain, following down in the chute H through the twopassage-ways 194 196, comes against the blades 202 and 204: of the valve200, respectively, from opposite directions, so that said valve isbalanced as to the lateral pressures and is not resisted in its verticalmovement by said pressures. The chute H being open at the ends, as at191, free access is given to the said valve or gate for removingobstructions and for assembling or disassembling the parts. By means ofthe construction and arrangement set forth the balanced gate 200 cutsoff the flow of grain from a single passage or discharge spout fordelivering grain from the passage-ways to a single grain-bucket.

The regulator P herein shown is sup posed to be the same regulator whichis described and claimed in the application of C. H. Cooley and F. H.Richards, Serial No. 340,284, filed February 13, 1890 but otherwell-known regulators operated by the dis charged grain, if suitablyconnected to actuate the said valve, may in some cases be employed.

Having thus described my invention, 1 claim- 1. In a regulator apparatusfor grain-weighers, the combination, with the supply-chute having onedischarge-passage and two supplypassages leading downward and meeting atthe discharge-passage below an open space protected by walls on thesides and top thereof, of the valve 200, consisting of vertical wallssurrounding said discharge-passage and constructed to move freely withinsaid walls, the regulator,and connections,substantiallyas described.from said regulator to said valve, the connection being made with thevalve through openings at the sides of the supply-chute between saidwalls.

2. Inaregulator apparatus forgrain-Weighers, the combination,substantially as shown, with a regulator and with the chute H, havingthe discharge-spout 65 and the supply-passages 194 and 196, leading tosaid dischargepassages, of the walls 193 between said passages 194 and196 and inclosing the space 191, which space extends through the sidesof the chute 11, forming said openings between said supply-passages, andthe valve 200, consisting of walls inclosing the upper end of saiddischarge-passage and having the carrier-bar extending outward from thechute through said side openings, said carrier-bar being connected withthe regulator.

3. In aregulator apparatus for grain-Weighers, the combination, with thegrain-weigher fralne-workcarryingaregulator,substantially as described,of a chute carried on said framework and having the passages 194 and196, leading to the discharge spout, the walls 193, between saidpassages and inclosing the space for the regulator-valve, and theregulator-valve 200, consisting of walls inclosing the upper end of saiddischarge-spout and carried by a bar extending through said space withinthe walls 193, guides, as 198 and 199, on the frame-work, andconnections from the regulator through said guides and carrying thevalve on the upper ends thereof.
